Sitecore XP 9.2 ARM templates – topologies and tiers

The following tables describe the Azure resource types and sizes that are provisioned with each of the Sitecore ARM templates found in the Sitecore Azure Quickstart Templates repository on GitHub. The single topologies are not supported for production sites – they are purely for development and test purposes.

The Performance rating sizes were determined by performance testing a simple marketing site and finding the smallest resource sizes required to hit the associated visits per month. The simple marketing site was mainly read-only, with no login activity and few xDB interactions. Dependent requests were not tested (for example, images, JS, CSS) and it is assumed these assets will be served by a CDN.

The following sizes and instance counts serve as a starting point for you when trying to figure out the Azure requirements for your site. You might need to adjust some or all of the sizes or instance counts when you have performance tested your application.

[1] Azure Search size refers to Search Unit (SU), which is the product of replica and partitions used by the Azure Search service (RS X P = SU). At a minimum, every service starts with 1 SU (one replica multiplied by one partition). See search units and SU combinations for more information.
As a cost saving measure the ARM Templates are initially set up with only 1 partition, and you can then add new partitions as required. However, from a budgeting point of view you can expect to increase to the number of partitions listed by the end of the first year.

[2] Items in parentheses beginning with i1, i2 and i3 are the isolated sizes in ASE V2.

[3] Azure Service bus has overages based on usage, EXM and Azure Automation has high levels of usage of Azure service bus, Cortex and scheduled tasks are in tasks < 100. There is 13 Million operations at time of writing that overages start being charged.

[4] Application Insights will have x3 overage storage costs due that is related to the amount of traffic. Allow approximately $10 for costs per month.
